This invention relates to im rovements in mountings for Venetian blmdswhereby to be opened to 'any desired extent without when such blinds areused adjacent windows having the fenestra sash, or .one in which one ormore sections swing u on horizontal axes, the Venetian blind may ereadil adjusted to different positions away from t e w ndow to permitthe movable section of the window in any way interfering with the blindor with its usual mode of operation.

One object of the present invention is to provide Venetian blinds withanimproved mechanism for movably supporting the blinds to enablethe'same to be readily and conveniently adjusted to accommodate windowsof the above mentioned t pe.

Another object of the invention is to provide such a structure whereinthe Venetian blind may be operated in theusual manner in so faras'adjustment of the blind itself is concerned, while at the same timeproviding a most convenient and efiicient arrangement for moving theblind to its various positions and maintaining the blind in a verticalposition whatever may be its relative position in respect of the windowwith which -,it is used.

Figure 11 is an end elevation of theparts 7 shown in Figure 10; and

Figure '12 is a side elevation ofthe upper portion of the blind andsupporting bracket.

Referring to the drawings and particularly to Figures 1, 3 and 4, theVenetian consists of the to number of slats 2 which are allconnectedtogether and to tl1e 'top or tilting bar 1 by tapes 3 which are securedto one side of the bar 1 and to the edges of all of the slats, as isusual in Venetian blind construction. In order that the objects of theinvention may be accomplished the Venetian blind is su ported solely atits top wherebyit 111a iie moved to various positions toward and i i'omthe window adjacent to which it is hungand at the same time maintain itsvertical position and be 0 erable inthe ordinary .way for raising anlowering the blind and changing t e angle of the slats'as desired.

In the preferred form of the invention this mounting of the blind andits adjustabilitv toward and from the Window is acbar 4 mounted abovethe tilting bar 1 and pivotally connected thereto. This connection ispreferably effected by means of an angle iron 5' engaging the under sideof the right-hand end of the sup ortin bar 4 and an angle iron 6engaging t e un er side of the left hand end thereof.

each angle iron, so; that said bar may rock upon said pmtles and therebychange the angular position of its slats 2. The means shown in Figure'1, the ends of the cord be- 1 ing connected to thetop and bottomrespectively of the bar 1, whereby pulling the outer strand of the cord-7 causes the slats to be rocked in one direction, while the oppositePintles, extending irom the bar 1, enter holes, one m bar 1 and a Ill"direction of movement is effected by pulling a the otherstrand ofreadily understood.

Theadjustment of the Venetian blind toward 'and from the window ispreferably the cord, as will be side of the blind, which arms pivotallysupport the bar 4 at upper ends of the arms, rackets 11 being providedfor this purpose, and also pivotally engage brackets 12 at their lowerends, Figure 1. By this arrangement it will beunderstood that as thearms 10 are moved outwardly the Venetian blind also moves outwardly butalways maintains its vertical position, being freely suspended from itstop ortion only. When the blind is closest to t e window as in Figure 4,the arms 10 are not quite vertical but are slightly inclined away fromthe window so that the weight of the blind is enough to cause furthermovement away from the window when such movement is permitted b themeans which normally restrain the lind flrom movement and whichmeanswill now be described.

Preferably there is provided a chain or cord, thetwo portions of which13 and 14 are connected to the bar l. the portion 13 near the left-handend and the portion 1d near the right-hand end of said bar. The portion13 passes through a sheave 15 of a bracket 16 and over a roller 17 in abracket 18. This latter bracket also carries a roller 19 situated in adifierent vertical plane from the roller 18, as shown clearly in Figure6, and the end 14 of the cord after passing over a sheave 20 carried bya bracket 21 passes over said roller 19 below which said two ends of thecord are united in a loop. The loop is formed by a ring 22 secured tothe two strands of the cord, such ring forming a stop to limitthe'movement of the blind away from the window. Preferably the bracket18 has a recess or depression 23 in its underside with which the ring 22engages. The cord 24 is secured to the loop and is manipulated manuallyto adjust the blind toward and from the window.

It is desired to avoid noise and jar when the blind is brought upadjacent the window and to accomplish this I have provided cushioningmeans in the form of bumpers 25 and 26 secured to the bark and sopositioned that they will contact respectively with abutments 27depending from the brackets 16 and 21.

The Venetian blind itself is moved up and down to shorten or lengthenthe blind by the usual cords 28 which are secured to the bottom slat andwhich pass about guide rollers on the bar 4 and depend for convenientmani ulation at the right side of the blind as siown at 29. The windowframe is shown somewhat diagrammatically, the top portion thereof beingindicated at 30 and the swinging sash portion at 31 pivoted on ahorizontal axis 32 whereby it may swing, as shown in Figure 3.

With the construction described avery convenient and efiicient meansliasgbeen provided whereby the blind may be adjusted to differentpositions parallel with the window to accommodate it of the degree ofopening to the swinging portion 31 of the window and-at the same timeprovide for manipulation of the blind in the usual way, in any osition.

In Fi \res to 12, I have shown a slightlv modified construction and onewhich differs from that just described principally in the fact thatinstead of providing the swinging arms 10 there is provided a bracket 33and a bracket 34, one at each side of the blind, and secured in anysuitable manner adjacent to the window frame. One of these brackets 33is shown in enlarged elevation in Figure 12, wherein it will beseen thatthe same is rovided with a slotfor supporting and ad usting the blind inits various positions. As in the first described construction, the topbar 35 of the Venetian blind is pivotally connected in the same manneras already described, to the second bar 36, but the manner'in which thissecond bar 36 is mounted for adjustment is different. At each end thisbar is provided with an angle piece 37 secured by screws 38 to the bar36. A stud 39 is screw-threaded or otherwise secured in one arm of theangle member and is provided preferably with a hexagonal portion 40-forming an abutment to en age the angle member, whereby it may esecurely screwed to said member. A flanlgedroller 41 is mounted on thestud and is held in place by means of a screw 42, said screw enga inginternal threads in the head of the stud. As shown inFigure 12, thebracket 33 is provided with a slot 43 which is enlarged at its right end44, the enlargement being of such size that the roller 41 maylie/inserted therethrough so that the flanges of the roller may thenongage on opposite sides of the track portion of the bracket, afterwhich the screw 42 is inserted. The cord connections, whereby the blindis adjusted toward and from the window, and whereby the blind is movedto lengthen or shorten the same, and to change the an ular position ofits slats, are the same as in t e first described form.

. It is to be understood that variations may be resorted to within thespirit of the invention as described, without departing from the spiritthereof. i
